CCTV Surveillance Design, Installation and Management


CCTV stands for Closed Circuit Television. It refers to a  technology that makes it possible for overt (visible) or covert (hidden) video system to be visible/ available in real time to a limited number of viewers.  In this case, CCTV signal is not broadcast.

CCTV system was initially developed as a means of security for banks and casinos; but with time, it has become pervasive  to an extend of being used in private properties, public spaces including stadiums, churches, mosques,  public transport, airports, etc. Their use in these areas has been triggered by a number of factors, among the top reasons being the rising insecurity in a number of places that did not present danger.

Terrorism has topped the list in the reasons why CCTV has increasingly  been deployed in most public and private places. Other reasons are break-ins, stock pilfering (in case of supermarkets, food places, petrol / gas stations, etc.), people committing misdemeanors, etc.


Kenvision Techniks Ltd undertakes CCTV installation projects in its own unique approach.


  1. A potential customer conducts us by way of visit to our offices, phone call, email or through a proxy
  2. A Kenvision technical staff (preferably a specifier) visits the customer premises to assess the need. On this visit the specifier carries a specification sheet that he/she uses to quantify the aspects of the installation (job). Here is a sample of  the Specification Sheet
  3. A Kenvision technical staff (preferably a specifier) visits the customer premises to assess the need. On this visit the specifier carries a specification sheet that he/she uses to quantify the aspects of the installation (job). He examines among other things:
    1. The vulnerability / risk assessment
    2. Environmental conditions (temperatures, humidity/moisture, dust, visibility (light levels), etc.
    3. The estimate of the number of cameras to be installed
    4. Control room location – if any
    5. Size of the property – area it covers
    • The specifier may get some of the information from existing property map/ design. He uses all the information he gets to compile a report which he presents to the project manager. This is the person who comes up with the estimated cost of the installation.
    • The estimates ( material and labour + maintenance) are passed to the customer for consideration as to whether to carry on or not.

  1. The customer approves the costs involved (if he does, may be after some negotiation).
  2. It is a requirement that the customer  pays upfront 60% of the total cost before any work is carried out.
  3. Kenvision Techniks prepares an agreement to be the binding document between itself and the customer. The document addresses responsibilities of both parties (see sample copy of the agreement from the downloads page) or simply click on the following link: SECURITY SYSTEM INSTALLATION CONTRACT
  4. Kenvision goes to the customer’s property and carries out the works according the agreement signed between the customer and Kenvision Techniks Ltd
  5. The clients examines the works carried out and certifies it complete as agreed in the specification sheet.
  6. Kenvision Installation teams clears the premises of any debris and wrappings emanating from the works that might have been introduced at the property.
  7. Customer signs the document signifying the project completion
  8. Kenvision Techniks presents to the customer the following documents within one week of project completion
  1. Final payment bill
  2. Equipment warranties (where applicable)
  3. Works guarantee for 1 year
  • A thank you note is sent to the customer


1.0   Policy Statement

CCTV can be effective in reducing or preventing crime if it is part of a broader crime prevention and community safety strategy, as such, it should not be implemented as the only means of addressing crime in public places.

Our CCTV projects are intended to reduce cases of theft and misconduct in the organisation premises. Like any other project, our CCTV projects will involve a degree of cost to the client, in terms of the cost of the installation, maintenance as well the impact it will have on personal privacy within the precincts of the organisation/ business premises.

Kenvision Techniks will ensure that this CCTV installation will always be done with respect for people’s privacy and their right to conduct or engage in lawful activities. Care will be taken to ensure that the scheme is not used to prevent access to the area covered by CCTV of those who have no criminal intent, but whose presence might offend against some ‘norm’ of behavior or dress.

Caution shall be taken:

  • The recording and retention of images shall be undertaken fairly and lawfully;
  • The purpose for which the information is being obtained shall be made known;
  • The information shall not be used for any other purpose than that proclaimed;
  • All users, staff and other persons in the precincts of property or areas under surveillance shall be made aware that they may be subject to CCTV surveillance;
  • The CCTV surveillance shall only be used to identify crimes occurring within the CCTV area;
  • The CCTV surveillance shall never be used to monitor or track individuals who have not obviously been involved in a crime;
  • The CCTV surveillance shall not be used for general intelligence gathering; and
  • Kenvision Techniks Ltd who is this case are the implementer of the scheme shall be made known and accountable for its operation.

2.1   The Challenge

Kenvision Company  will carry out a detailed survey of the area under surveillance and armed with experience in the field of public / social control techniques is proposing to install/ deploy CCTV and/ or alarm surveillance system that will make it possible to have a real time total visibility of the Areas under surveillance.

The following is the detailed proposal of the system functionality, associated costs and the strategic approach to addressing the associated issues.

We use proactive (passive as well as active) technologies to enable the management ensure security for the stock, the users and the staff. This will be done through

1. Installation /deployment of video cameras that would monitor activity in all the areas listed 24/7, by building a reliable network that could support the streaming video traffic,

We intend to provide a reliable solution that would address the following issues:

  • Provide high-capacity video surveillance traffic
  • Ensure reliability and performance and also remain cost effective
  • Adapt to future bandwidth requirements
  • Deploy quickly with minimal maintenance

2.1.1 Performance Justification

When deployed, the cameras will record 24 hours a day and send the information to a remote storage to be later analyzed for evidence of criminal activity (ies) or other antisocial behaviors

2.2   Environmental Assessment

Kenvision Techniks has already carried out initial environment assessment which will guide us in making the right decisions regarding where to locate the cameras. In all, we have assessed:-

  • Lighting levels including shadowing, minimum lux levels, type and height including varying lighting levels in open areas as opposed to under awnings etc, obstructions to fields of view
  • Recommended height of equipment above ground to deter potential vandalism
  • Clear field of view from camera height, taking into account building structures
  • Direction of sun, including sunrise and sunset “blooming” effect on the cameras
  • Proximity of private areas and the view of the cameras
  • Possibility of the accompanying lighting intruding upon the surrounding areas and impinging upon the public’s enjoyment of that area.

 2.3   System Design
